The actual simulator rules
One spin draws twelve independent fair open/closed cells in a three-by-four board. Raw score is the area of the largest all-open axis-aligned rectangle, if that area is at least three; otherwise it is zero. Count one maximum area, without summing rectangles. One whole stake covers the board.
These are this guide's original rules. Visual resemblance, game-category names and search snippets provide no evidence about an external commercial game.
Worked scoring examples
A completely open board scores twelve. One completely open row scores four. Just two adjacent open cells score zero. A rectangle may span several rows and columns, but every cell inside it must be open.
Exact expected gross return
Enumerate all 4096 equally likely outcomes and calculate a separate exact mean for each weighting mode. Choose Low, Medium or High before a round. Positive raw scores receive square-root, identity or square weighting respectively; zero remains zero.
Gross virtual credit equals the whole captured stake times 0.96 times observed weight divided by the corresponding exact mean. Every mode has 96% exact expected gross return. There are no separately paid row shares. The stake was deducted at launch, so gross credit includes the stake component and is not net profit.
Modes preserve positive-score frequency while changing positive credits after normalisation. The expectation is neither a 96% chance of winning nor a session-balance guarantee. Past results do not make a favourable next outcome due.
Captured settings and the persisted wallet
A new browser wallet starts with 1,000 free virtual coins. Settled balance and fractional-credit carry persist in localStorage. Reload does not replenish settled funds; clearing cache may leave localStorage intact. Fractions accumulate before whole coins are credited.
A spin captures one whole stake and mode. Controls and refill lock during settlement and an active automatic queue. Auto launches at most ten rounds; Stop cancels future launches while active results settle. Refill remains locked until all active results and queued launches finish. Optional manual refill is available while idle with balance below ten; it sets balance to 1,000 and preserves carry. It is not automatic and does not add 1,000.
Local storage and external requests
The browser retains settled balance and fractional-credit carry as local game state. These records are not an online account and provide no recovery or device synchronisation service. Clearing site storage can remove them; cache deletion alone may not do so.
Pages request Google Fonts and a Statinside analytics script. Server/CDN logs and external requests may expose IP address, browser, device and request details. No anonymity, cookie lifetime, absence of profiling or complete third-party processing description is established. Having no personal-information form does not establish that browsing creates no personal data record.
Limits of external claims
No outside business identity, official domain, commercial safety verdict, licence, financial service or support channel is authenticated here. A logo, search ranking, name or professional interface does not establish these facts. HTTPS encrypts transport to a selected host; it does not certify the host business.
The simulator cannot test external responsiveness, commercial payouts, accounts, funds or transactions. No commercial testing history, regulator endorsement or named editorial team with verified contacts has been established for these pages.
Browser play and application evidence
No authenticated native app, APK, publisher certificate, package version or update channel is supplied here. The simulator runs in a browser without installation. A filename, logo, file size or version label alone cannot establish the origin or safety of a package.
A hash compares bytes against a trusted reference; it does not establish that the referenced software is safe. This page provides no installation link or instruction to bypass device warnings. Browser-game results do not assess an external app.
Adult use and time boundaries
This guide and simulator are for adults aged eighteen or older. That is this website rule, not a determination of gambling eligibility, regional availability or local authorisation. Jurisdiction-specific questions require an authoritative local source.
Choose a stopping time outside the game, take breaks and leave when the time arrives. A free refill is optional, not an obligation to continue. If play crowds out other activities or feels difficult to stop, seek qualified local support; no diagnosis, symptom threshold or treatment claim is supplied here.
Stop future launches without chasing results
Stop cancels future automatic launches while active results settle under their captured settings. Closing the page ends participation. A virtual result creates no obligation to recover an earlier wallet balance.
Increasing stake scales debit and possible credit without raising expected return per coin. Mode changes do not raise positive-score frequency for a fixed probability condition. Choose a stopping time independently of the last result.
Scope of this independent guide
viv55.info publishes editorial pages and its own Max Rectangle browser simulator. A matching name or search query establishes no outside operator, official domain, licence, app, commercial catalogue, support contact or regional availability.
The simulator uses free virtual coins with no cash value. There are no deposits, withdrawals, commercial accounts or prizes here. Its results establish no external game mathematics, financial safety or commercial affiliation.
Frequently asked questions
Is this an authenticated operator website?
No. This guide provides its own simulator and authenticates no outside commercial affiliation.
How is raw score defined?
One spin draws twelve independent fair open/closed cells in a three-by-four board. Raw score is the area of the largest all-open axis-aligned rectangle, if that area is at least three; otherwise it is zero. Count one maximum area, without summing rectangles. One whole stake covers the board.
What is an example of the score?
A completely open board scores twelve. One completely open row scores four. Just two adjacent open cells score zero. A rectangle may span several rows and columns, but every cell inside it must be open.
What do the weighting modes change?
Low, Medium and High apply square-root, identity and square weights to a positive raw score. Zero stays zero, and each mode is separately normalised.
What does 96% describe?
Exact expected gross virtual return relative to captured stake under the stated probability condition. It is not a win probability or session guarantee.
Does reload refill the wallet?
No. Settled balance and fractional-credit carry persist in localStorage.
When is refill available?
Only while idle with balance below ten. Manual refill sets balance to1,000 and preserves carry; it does not add1,000.
Does Stop cancel an active result?
No. It cancels future automatic launches while active results settle.
Is an app needed?
No. The simulator runs in a browser. No outside APK or publisher is authenticated here.
Can these credits be withdrawn?
No. They have no cash value and cannot be redeemed or transferred.
Does having no account guarantee anonymity?
No. External font and analytics requests and server/CDN logs may expose IP, device and request details.
Does the demo establish external safety?
No. It cannot test an outside business, commercial game, account or payment service.
